I would like to build the sources on OSX to get gcj. I've downloaded gcc-core-4.1.1.tar.bz2, gcc-g++-4.1.1.tar.bz2, and gcc-java-4.1.1.tar.bz2 and then un-tarred them. Not sure at this point what to do to configure the build and then invoke the bootstrap build. Anyone know how I should proceed? Thanks in advance. Michael
